CENTRIFUGAL LIQUID-SEPARATOR.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed December 13,1905. Serial No. 291,544.

To rtZZ whom it incl/y concern:

Be it known that I, DELOSS W. JORDAN, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Centrifugal Liquid-Separators, of which the following is a specificatron.

My invention relates to improvements in centrifugal liquid-separators;and the object of my improvement is to provide a centrallyperforatedcream-screw for the exit of separated cream or the separated lighterconstituent of the liquid so constructed as to permit of the adjustmentof the inner opening of said exit to space it nearer to or farther awayfrom the axis of the separator-bowl that liquids having varying degreesof the lighter constituent may thus be properly separated.

This object I have achieved by the means which are hereinafter describedand claimed,

and which are illustrated in the accompanying drawings, in which Figure1 is a vertical transverse axial section of the cover of a centrifugalliquid-separator equipped with my improved creamscrew. Fig. 2 is a sideelevation of the creamscrew, on a larger scale, showing its recessedlower end. Fig. 3 is a side elevation in perspective of theincasing-cylinder with the cream-screw inclosed therein; and Fig. 4 is aside elevation of the said cylinder, showing its slotted side.

Similar letters of reference refer to similar parts throughout theseveral views.

I have shown in Fig. l a separator-bowl cover a of a common type, buthaving thinner walls than those which have the cream-screw threadedwithin their walls. Instead of thus placing the cream-screw d I haveprovided a cylinder 0 for its reception interiorly threaded, saidcylinder bein aflixed to the inner cylindrical periphery (I of the saidcover a. This cylinder 0 is slotted, as shown in Fig. 4, and its top isleft open and its lower end closed. The slot f in said cylinder 0 is solocated with reference to the inner periphery of the cover a that eachone of its vertical edges lies in the same vertical plane whichintersects the axis of the bowl.

the slot g.

The cream-screw d has the usual drivingslot e across its top surface andis provided with a vertical axial perforation extending to A slot g iscut horizontally into the lower side of the cream-screw d, as shown inFig. 2. When the cream-screw has been inserted into the cylinder 0, asshown in Fig. 3, to a sufficient distance, the slot 9 of said screwallows communication to be established between the slot f in thecylinder and the axial perforation in the screw. When it is desired toadjust the entrance of the creamexit to vary it to or from the axis ofthe bowl, the cream-screw d is but slightly turned forward or back,which brings the edge of the slot 9 nearer to or farther away from thesaid axis and permits the proper adjustment for varying quantities ofcream in the milk.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In a centrifugal liquid-separator, an ada justable exit for thelighter constituent of the liquid, composed of a fixed hollow cylinderwith open top and closed bottom, and provided with a lateral slot incommunication with the interior hollow, and a plug provided with alengthwise perforation and rotatably fitted within said cylinder, thelower portion of said plug being slotted to effect communication betweensaid perforation and the said lateral slot in said cylinder.

2. In a centrifugal liquid-separator, an adjustable exit for the lighterconstituent of the liquid, composed of an interiorly-threaded fixedhollow cylinder with open top and closed bottom, and provided with alateral slot in communication with the interior hollow, and anexteriorly-threaded plug pro vided with a lengthwise perforation androtatably fitted within said cylinder, the lower portion'of the plugbeing slotted laterally to said perforation.
